If you are putting in a 60 amp service, then you may need #4.
You might want to see what your current requirements are, and that will determine the breaker and wires size.
The length does play into the equation, But code seems to play different, That depends on local codes.
Maybe your friend could make sure that you can meet your code. He should know the requirements.
#4 American Wire Gauge aluminum Service Entrance four conductor cable is good for 50 amps. It does not need to be installed in a conduit. Lowe’s or Home Depot will cut to length or any electrical supply house.
Electrical Metallic Tubing is a bad idea to use for the final connection to the hot tub as the chemicals used in the tub will cause it to rust. Non-Metallic Flex is a better idea for the final run of copper THW conductors.
Take you age and multiply it by 10 and you haven’t come close to the number of these tubs I have installed in my life time so listen to experience.
The SER cannot be used for the exterior portions to feed the hot tub. The grounding conductor needs to be insulated.
There is a 6' limit on the flex to feed the tub.
JW is correct, old farts know some stuff.....
Just meet your local code... And get it done...
6 feet from the outside of the tub in the 2011 edition
Is it legal to have a 3 conductor feed going outside?
I was under the impression all outdoor 220 fixtures were 4 conductor only.
